AV Fistula Surgery for Dialysis Patients in Borivali, Mumbai: Procedure & Care Tips

For individuals managing Chronic Kidney Disease (CKD) or End-Stage Renal Disease (ESRD) who require maintenance hemodialysis, establishing a dependable, long-lasting vascular access point is essential. An Arteriovenous (AV) Fistula is globally recognized as the gold-standard vascular access technique due to its superior patency rates, lowest complication frequency, and minimal risk of systemic bloodstream infection.

What is an AV Fistula and How Does it Work?

An AV Fistula is a minor surgical connection created between a high-pressure artery and a adjacent vein, typically in the non-dominant forearm or upper arm. Under normal circumstances, veins are thin-walled and carry low-pressure blood back to the heart. Connecting the artery directly into the vein diverts arterial blood flow into the vein, causing the vein wall to thicken, dilate, and mature over 4 to 8 weeks. Once fully matured, the enlarged vein can easily accommodate repeated needle insertions required for high-efficiency dialysis sessions.

Types of AV Fistulas Created at PRS Clinic

Micro-vascular surgeon Dr. Harsh R. Shah evaluates forearm and arm vasculature using Doppler ultrasound mapping to choose the ideal anatomical site:

• Radiocephalic Fistula (Brescia-Cimino): Created at the wrist between the radial artery and cephalic vein. This is the primary choice as it preserves proximal arm veins for future access needs.
• Brachiocephalic Fistula: Created at the inner elbow crease between the brachial artery and cephalic vein. Provides robust blood flow for larger arm vessels.
• Brachiobasilic Transposition Fistula: Utilized when superficial veins are unsuitable; the deep basilic vein is dissected, mobilized, and transposed superficially under the arm skin.

Post-Operative Fistula Maturation & Maintenance Rules

To ensure long-term AV fistula survival and function, patients must follow essential daily precautions:

1. Feel the Thrill Daily: Check your fistula daily by placing fingers gently over the surgical site to feel a continuous vibrating pulse ("thrill"). If the thrill stops, contact your surgeon immediately.
2. Squeeze Ball Exercises: Perform stress ball squeezing exercises 3 to 4 times daily starting 10 days post-surgery to accelerate vein wall thickening and maturation.
3. Avoid Arm Constriction: Never allow blood pressure readings, blood draws, or tight clothing/watches on the arm with the AV fistula.
4. Avoid Heavy Pressure: Do not sleep on the fistula arm or carry heavy grocery bags resting on the access arm.
